Introduction
The LADWP Meter Leader Exam assesses a candidate’s readiness to supervise and
perform work on electric metering systems within the Los Angeles Department of
Water and Power. The examination evaluates foundational electrical theory, practical
metering knowledge, regulatory compliance, and safety practices. Through a
combination of multiple-choice and scenario-based questions, the exam emphasizes
real-world application and decision-making in field environments. Candidates must
demonstrate not only technical proficiency but also ethical judgment and adherence
to established procedures. This assessment is designed to identify individuals
prepared to lead crews, ensure accurate metering, and maintain the highest
standards of electrical safety.
SECTION ONE: QUESTIONS 1–50
1. What is the primary purpose of an electric utility meter?
,A. To increase the voltage supplied to a customer
B. To measure the electrical energy consumed by the customer
C. To protect every branch circuit from overload
D. To automatically disconnect service during a fault
🟢 Correct Answer: B. To measure the electrical energy consumed by the customer
🔴 Explanation: An electric utility meter measures electrical energy used over time,
typically expressed in kilowatt-hours (kWh), which provides the utility with billing
information and system monitoring data.
2. Which unit is commonly used by electric utilities to bill customers for energy
consumption?
A. Ampere
B. Volt
C. Kilowatt-hour
D. Ohm
🟢 Correct Answer: C. Kilowatt-hour
🔴 Explanation: A kilowatt-hour represents energy consumption equal to one
kilowatt of power used for one hour and is the standard billing unit for residential
and commercial electric service.
3. Before working on an electrical service or meter installation, what should be
the first priority?
A. Establish a safe work condition according to applicable procedures
B. Remove the meter immediately
C. Test the customer's appliances
D. Increase the service voltage
🟢 Correct Answer: A. Establish a safe work condition according to applicable
procedures
,🔴 Explanation: Electrical utility work requires deliberate hazard assessment and
adherence to established safety procedures, including isolation, lockout/tagout,
voltage verification, and required PPE before handling equipment.
4. What instrument is commonly used to measure voltage?
A. Megohmmeter
B. Clamp meter
C. Voltmeter
D. Watt-hour meter
🟢 Correct Answer: C. Voltmeter
🔴 Explanation: A voltmeter is designed to measure electrical potential difference
between two points and is connected in parallel with the portion of the circuit
being measured.
5. What does an ammeter measure?
A. Electrical current
B. Resistance
C. Energy consumption
D. Frequency
🟢 Correct Answer: A. Electrical current
🔴 Explanation: An ammeter measures current expressed in amperes. Current
measurements can be made with various instruments, including clamp meters that
sense current without disconnecting the conductor.
6. Which electrical quantity is measured in ohms?
A. Power
B. Current
, C. Resistance
D. Voltage
🟢 Correct Answer: C. Resistance
🔴 Explanation: Resistance is measured in ohms and represents opposition to
current flow. Resistance measurements help identify continuity problems, open
circuits, shorts, and equipment conditions.
7. What is the safest general practice when using a portable electrical test
instrument?
A. Use it regardless of visible damage
B. Inspect the instrument and leads and select the correct function before testing
C. Hold exposed metal portions while testing
D. Use the highest current range for every measurement
🟢 Correct Answer: B. Inspect the instrument and leads and select the correct
function before testing
🔴 Explanation: Damaged test leads, incorrect meter settings, or inappropriate
ranges can result in equipment damage, inaccurate readings, arc flash, shock, or
other hazards.
8. In a typical single-phase residential service, what is the purpose of the
grounded service conductor?
A. It provides the intended return path for unbalanced load current and establishes
the system reference to ground
B. It always carries the entire service current
C. It replaces all overcurrent protection
D. It is used only for lighting circuits
🟢 Correct Answer: A. It provides the intended return path for unbalanced load
current and establishes the system reference to ground
